The Prime Minister:
I welcome the right hon. Gentleman to his new position. He asked what is an active aging strategy. The best active aging strategy that I know of is to be either Leader of the Opposition or Prime Minister--we shall see how we both fare in that regard. I welcome the fact that the right hon. Gentleman agreed with much of the Denver communique, particularly the points about organised crime, Hong Kong and the participation of Russia. That is precisely what I am saying in relation to G7 summits. It is important that they concentrate on fewer issues, but go through them in depth.

we have the best chance of making a significant contribution to reducing greenhouse gas emissions, which is what we all want to see.

Mr. Paddy Ashdown (Yeovil):
I join the Prime Minister, first, in welcoming the right hon. Member for Richmond, Yorks (Mr. Hague) to leadership of the Conservative party. I think that I am right in saying that he is the sixth leader of one or other of the two parties, Conservative and Labour, that I have seen since becoming leader of mine. I wish him--[Interruption.] Look how I look, Madam Speaker? I look younger every day. I wish the right hon. Gentleman well in his task, which most people regard as impossible.

involved to achieve that. I have been saying that for some time, as has President Clinton. If pressure to reach agreement is taken off those countries, there is a risk that the whole process will slip backwards; that would be desperately unfortunate. I agree whole-heartedly with the right hon. Gentleman on that.

Mr. Tam Dalyell (Linlithgow):
On Africa, does the Prime Minister recall that the one subject about which President Mandela wrote a personal letter to the previous Prime Minister was his unease about Libyan sanctions? The unease felt about Lockerbie has been outlined in 11 Adjournment debates. Will the Prime Minister also reflect on the Channel 4 programmes that cast grave doubt on whether the Libyans were responsible for the brutal and wicked murder of WPC Yvonne Fletcher? Before dismissing them merely as television speculation, will he take into account the fact that to do so he would have to suppose that George Styles, the senior ballistics officer of the British Army, does not know much about ballistics, that Hugh Thomas, who was the senior consultant at the Royal Victoria hospital in Belfast, does not know much about the angles at which bullets enter bodies, and that Bernard Knight, as the distinguished Home Office pathologist in charge of the Cromwell street investigation, does not know about pathology? Will he take this matter seriously?

The Prime Minister:
As I said to my hon. Friend last week, the Libyan sanctions will remain until Libya complies with the United Nations Security Council resolutions. The Channel 4 programme was a follow-up to the original programme that was made some time last year. The continuing investigation into the murder of WPC Fletcher is a matter for the police, and anyone who has new evidence relating to the crime should pass it to them. The original extensive investigation by the Metropolitan police forensic science laboratory and the pathologist Dr. Ian West concluded that she was killed by a bullet fired from the Libyan People's Bureau. Every piece of new evidence has been reviewed, but my advice is that the view prevails that she was killed by a bullet from the Libyan People's Bureau.
